Abstract:This research is qualitative research with the aim of (1) to find out the description of mathematical communication skills of male and female students in solving mathematical problem-solving questions, (2) to find out different information about mathematical communication descriptions in solving problem-solving problems in terms of gender. The subjects of this study were two class VII students of SMP Negeri 2 Labakkang, namely one male and one female student who had the highest problem-solving test scores. The procedure of data collection is done by observation, tests of problem-solving and interviews. The research instrument was used in the form of observation sheets, tests of problem solving, interview guidelines. Data analysis techniques are carried out by testing credibility, transferability, dependability, and conformability. The results showed that the mathematical communication skills of male gender subjects were lower than those of female gender subjects. The location of differences in mathematical communication skills between male and female gender is that the indicators write answers according to the purpose of the problem and make conclusions in writing using their own language.

Abstract:The lack of use of teaching materials that are able to construct learners to understand mathematics learning in schools causes the achievement of students' mathematical skills are still in the low category. This study aims to develop a valid, practical and effective LKPD based on RME with maritime context. This research is a type of Research and Development (R&D) research with a limited ADDIE development model, they are Analysis, Design, Development (ADD) stage. Data in the study were collected by the test and questionnaire methods. The research instruments used were expert validation sheets, student questionnaire response sheets, and test sheets. Data were analyzed with descriptive analysis to measure the validity of LKPD, Rasch modeling to measure the practicality of LKPD, and compare individual and classical minimum completeness criteria from students' post-test results to measure the effectiveness of LKPD. The results showed that LKPD based on RME fulfilled valid criteria with the dominance of the assessment in the good category, practical criteria with the dominant response of students in the practical category, and effective with a percentage of completeness of 87%.

Abstract:This study aims to see how the implementation and students’ perceptions of e-learning type blended learning in Mathematics Capita Selecta course. The e-learning in this study utilized the Syarah portal, an online learning application developed by Universitas Maritim Raja Ali Haji (UMRAH) responding to the 4.0 era. This online learning using Syarah was the first time applied to research subjects, namely 35 students of Mathematics Capita Selecta Course year 2019. The data was collected from the results of the researchers' observations during the learning process and students’ responses to the questionnaire. The data were analyzed qualitatively to describe how the implementation of e-learning and how students’ perceptions about e-learning Syarah in supporting them to learn. The results of the analysis show that the Syarah system and students are ready for the implementation of online learning. Students’ confusion only occurs at the initial meeting of each type of e-learning activities designed by the researcher. Hereinafter, students could carry out learning well, even independently, but with clearly stated instructions. In addition, students were actively involved during the e-learning process. It also reveals that students felt more open to engaging in e-learning activities than when they were in class. In general, students gave positive responses to the use of Syarah in supporting blended learning.

Abstract:This study is the descriptive research that aims to determine student learning activities when applied MEAs approach and learning outcomes after applied MEAs with subject relation and function. The subjects were students of class VIIID junior high school number 1 Indralaya Utara, amounting to 32 students. The data were collected using observation dan test and analyzed descriptively. The research result to shows the implementation of student learning on the MEAs approach included in the good category. From result learning get 29% students included in the very active category, 19% students included in active category and 26% students included in quite an active category while students learning outcomes included pretty good when 7% students included in very good category, 33% students included in good category and 40% students included in pretty good category, with an average value is 66,1.

Abstract:This study aims to describe the thinking ability of class X MIA 2 of SMA Negeri 2 Tanjungpinang in solving functional problems. Research subjects are a total of 40 students who have received material of function before. Instrument for the assessment of students’ higher-order thinking skills consisted of 10 questions. Data were analyzed using the average method as an explanation of students’ higher-order thinking skills. Considering the high level of students in terms of high-level thinking ability indicators, namely analyzing, evaluating and creating. The results obtained on the average analyzing indicator obtained is 47.85 with enough category, the indicator of evaluating with an average of 12.50 with very less categories. And the indicator of creating with an average of 19.02 with very less category.

Abstract:This study aims to examine the increase in student’s mathematical conceptual understanding ability using differential equation teaching materials using Guided Discovery assisted by Mathematica software. This study is a quasi-experimental with pretest posttest Control Group Design. The research subjects were the sixth semester students of Mathematics Education Study Program, Muhammadiyah University of Tangerang, with a sample of as many as two classes selected by simple random sampling technique. The experimental class uses differential equation teaching materials with the Guided Discovery method assisted by Mathematica software and the control class using ordinary teaching materials. The results of the study showed that an increase in mathematical conceptual understanding ability of the experimental class was higher than the control class. The average normalized gain of students in the experimental class is in the high and medium categories. While the control class is in the medium and low category. The normalized gain difference in the experimental class is better than the control class.

Abstract:Rendahnya Kemampuan Koneksi Matematis (KKnM) siswa merupakan permasalahan utama penelitian. Permasalahan di lapangan siswa kurang mampu mengkoneksiakan konsep/ide matematika dalam pemecahan masalah matematis. Dengan demikian perlu suatu pendekatan pembelajaran yang memacu siswa untuk menyelesaikan masalah dengan feleksibel yaitu pembelajaran dengan pendekatan open-ended. Tujuan penelitian ini adalah untuk mengetahui peningkatan KKnM siswa SMP melalui pendekatan open-ended. Untuk mencapai tujuan tersebut dilakukan penelitian eksperimen semu dengan rancagan Nonequivalent Control Group Design. Populasi penelitian adalah siswa kelas VII SMP Negeri 5 Padangsidimpuan. Sampel yang dipilih adalah kelas VII-5 sebagai kelas eksperimen dan siswa kelas VII-6 sebagai kelas kontrol. Penelitian yang dilakukan menunjukkan hasil melalui uji independen sampel t-tes diperoleh signifikansi hasil pretest dan posttest sebesar 0,004 yang berarti terdapat perbedaan rata-tara antara KKnM siswa kelas eksperimen dengan kelas kontrol. Selanjutnya melalui uji N-gain diperoleh nilai rata-tara N-gain kelas eksperimen sebesar 0,48 yang berarti nilai peningkatan berada pada kategori sedang dan pada kelas kontrol diperoleh nilai N-gain sebasar 0,28 yang berarti berada pada kategori rendah. Dengan demikian disimpulkan bahwa KKnM siswa melalui pendekatan open-ended berbeda secara signifikan dengan KKnM siswa dengan pendekatan konvensional dan KKnM siswa yang diberi pembelajaran dengan pendekatan open-ended lebih baik dari pada KKnM siswa dengan pendekatan konvensional.
